Scientists from the Drug Discovery Unit (DDU) at the University of Dundee - working together with partners at the University of York and the Structural Genomics Consortium in Toronto - have made a major breakthrough in identifying new treatments for a fatal disease which infects tens of thousands of Africans each year.

ANN ARBOR, Mich.---The skull of a juvenile sauropod dinosaur, rediscovered in the collections of Pittsburgh's Carnegie Museum of Natural History, illustrates that some sauropod species went through drastic changes in skull shape during normal growth.
University of Michigan paleontologists John Whitlock and Jeffrey Wilson, along with Matthew Lamanna from the Carnegie Museum, describe their find in the March issue of the Journal of Vertebrate Paleontology.
WEST LAFAYETTE, Ind. - The unmet or unrealistic expectations adoptive parents often have is a recurring theme in postadoption depression, according to research from Purdue University.
In gastric cancer patients who have had part or all of their stomach removed, the hormone ghrelin may lessen post-operative weight loss and improve appetite, according to a new study in Gastroenterology, the official journal of the American Gastroenterological Association (AGA) Institute.
As anyone who has suffered from a cold or flu knows, a high temperature is an unpleasant but important side effect of the body's immune reaction when fighting off pathogens. Laboratory studies, in which the immune responses of animals could be observed in detail, have shown that these responses display significant variations. Why doesn't every organism defend its body at the maximum possible level of intensity?
The "vegetable lamb" plant — once believed to bear fruit that ripened into a living baby sheep — produces substances that show promise in laboratory experiments as new treatments for osteoporosis, the bone-thinning disease. That's the conclusion of a new study in ACS' monthly Journal of Natural Products.
A Kansas State University researcher is exploring the use of Chinese wolfberries to improve vision deficiencies that are common for type-2 diabetics.
Dingbo "Daniel" Lin, K-State research assistant professor of human nutrition, is studying wolfberries and their potential to improve damage to the retina. His findings show that the fruit can lower the oxidative stress that the eye undergoes as a result of type-2 diabetes.
How many gallons of water does it take to produce $1 worth of sugar, dog and cat food, or milk? The answers appear in the first comprehensive study in 30 years documenting American industry's thirst for this precious resource. The study, which could lead to better ways to conserve water, is in ACS' Environmental Science & Technology, a semi-monthly journal.
Scientists in the United Kingdom are reporting evidence that consumption of insects contaminated with a toxic metal may be a factor in the mysterious global decline of meat-eating, or carnivorous, plants. Their study describes how meals of contaminated insects have adverse effects on the plants. It appears in ACS' semi-monthly journal Environmental Science & Technology.
Scientists have uncovered what could be a very important clue in answering one of the most perplexing questions about cancer: why does it spread to the liver more than any other organ? In a new research report published in the April 2010 issue of Journal of Leukocyte Biology (http://www.jleukbio.org), scientists from New York University describe experimental results suggesting that the immune system may be the reason.
London (March 31, 2010) – In recent years the UK Government has been placing less emphasis on the idea of probation as a form of rehabilitation, instead re-framing it as 'punishment in the community,' with a focus on protecting the public. However, according to new research appearing this month in the Probation Journal published by SAGE, recently recruited probation officers may not be completely in step with the Government's approach.
Women conducting research in the life sciences continue to receive lower levels of compensation than their male counterparts, even at the upper levels of academic and professional accomplishment, according to a study conducted by the Mongan Institute for Health Policy at Massachusetts General Hospital. In their report in the April issue of Academic Medicine, the research team also finds differences in the roles female faculty members take as they advance in their careers.
"Blindsnakes are not very pretty, are rarely noticed, and are often mistaken for earthworms," admits Blair Hedges, professor of biology at Penn State University. "Nonetheless, they tell a very interesting evolutionary story." Hedges and Nicolas Vidal, of the Muséum National d'Histoire Naturelle in Paris, are co-leaders of the team that discovered that blindsnakes are one of the few groups of organisms that inhabited Madagascar when it broke from India about 100 million years ago and are still living today.

Changes are urgently needed to end the secrecy surrounding approval of new drugs in Europe, argue experts on bmj.com today.
Questions about the benefits of the flu drug oseltamivir in otherwise healthy people have fuelled debate about the secrecy surrounding the documentation submitted by drug companies to obtain approval of new drugs, write Silvio Garattini and Vittorio Bertele' from the Mario Negri Institute for Pharmacological Research in Italy.
